Application M To all whom it 'may concern:

Be it known that I, EDWARD A. LEvrcK, a citizen of the AUnited States, residin at Halifax, in the county of Dauphin and tate of Pennsylvania, have invented certain new and useful Improvements in Chair Seats; and I do hereb declare the followin to be a full, clear, am exact description o the invention, such as` will enable others skilled in the art to which it appertains to make and use the same.

I have produced an improved upholstered chair-scat or back ofnovel construction and as an article of manufacture adapted to be fastened to the -chair-frame, and in the claims appended hereto I will set out the precise construction wherein my improvement resides, in connection with the accompanying drawing, in whicl1,-

Figure 1 shows in perspective an u holstered chair-seat, the cover and the aseplate being partly broken awa f at the front edge to show the inturned or olded edge of the base-plate as the means of fastening to the underside 'thereof a bracing border frame provided with integral spurs or prongs as the means of attaching the cover to said border frame and producing thereby a braced seat ready for being fastened tothe chair frame.

Fig. is a vertical section of the same showing the manner of securmg the cover to the border frame and the seat to the undersidel of the chair-frame. Fig. 3 shows in perspective theunders'ide of the base-plate and the separate border plates having the integral cover attaching spurs and secured to the baseplate by inturned or folded edge thereof the tastened edges of the cover being partly broken away. "Fig 4 shows in perspective one of the border bracing strips vand its integral cover attaching s urs and fastening tongues.V Fig. 5 shows the underside of the seat corner and the lapping ends of the strips,

the base lap being broken.

The sup ort or base 1, of the seat is of sheet meta conforming to the shape of the seat and having an underlap 2, around its edges .of about a quarter of an inch wide. A metal strip 3, about an inch wide and formed with a plurality of inte ral spurs or prongs 4, standing downward a ong the edge of the underlap, is set u on thebase beneath its edge underlap and tile latter being hammered down upon the strip secures it to the lap and to the base so that the ends of two of these spurred strips being lapped at the ends as at i Aspecimen e: um rame.

which it is engaged with the spurs and the latter beine then hammered down inward on the cover cllamp it to theborder frame.

Before the cover is secured .a filling of yielding material 6 is properly placed and packed between the covering and the base. he seat may be fastened at its underside to the chair-frame and for this purpose two or more of the l'strips may have one or more integral tongues 7, standing downward in position to be nailed to the inner 'edge of the chair seat supporting frame. With these fastening tongues the border frame will then the base and also the means of fastening the seat to the chair. The provision of the under edge lap of the base, while forming a bracing rib, serves the more important purpose as a fastener for the border frame and these two bracing elements give the advantage of using cheap and thin sheet tin for the seat-base. By making the border-frame of sep arate strips they can be set separately under the base under-lap and all the strips then clamped together by the overlapped base edges.

The provision for fastening the seat to the frame `beneath the seat, renders it convenient for removing the seat and o ening the cover to renew the filling. It w' be noted that each strip of' the border frame, is clamped along its edge-to the base by the arallel underlapping part, 2 of the base. Fach end 5, of each side str'ip is lapped upon the correspondin ends of the connecting strips and under t e edgelappingpart 2 of the base, so that one edge and each end of each strip is clampedrmly upon the base by its underlap, so that the border frame practically forms a supplemental bottom for the seat.

When the se arate spurred strips are secured by the c amping function of the base underlap to the underside of the base, they form, by the lapping of the ends of said strips, a connected border frame; and in assembling-the strips to form'said frame, it is only necessary to place them within the base lap and hammer it down thus making the base the meansI of securing the border-frame,

under the base-lap, has a row of lslits by serve as the means of fastening the cover to n and the latter the means of securing the ('IOVCI'.

i I claim:

1. A chair-seat, comprising a base of sheet metal formed'with an underla around its edges, a border-frame formed o strips, each,l with integral spurs or prongs, and adaptedv to be set under said underlap and clamped thereto` and to the base, said strips forming a border strengthening and bracing frame for the base, and a cover fastened to the spurs of the separate border-frame.

2. A chair-seatcomprising a base of sheet metal formed with an underlap around its edges,- a border frame formed of separate strips each' with integral spurs and adapted to be set under said underlap and clamped' thereto and to the base, said strips having integral tongues on their inner edges standing downward and adapted to be fastened to the chair frame'beneath the seat, and a cover fastened to the spurs of .the said separate border-frame. v

- 3. 4A chair bottom consistin of a base of sheet metal formedwith an un erla'p around its edges, a frame, formin aborder for the base and secured thereto y' said under1ap,f and having 'integral'spu'rs' along the edges of' said under1ap,1fmeans de ending froml said,"y border frame' 'and adapte to be fastened to the chair-frame beneath the bottomy ofthe seat, and a cover fastened to the spurs ofthe separate border-frame,` v 4. A'chairy bottom comprising a' base ofY I sheet metal form-ed with an underla around its edges, a border-frame compose of separate strips 'of sheet metal each having integral lspurs and each fastened to the base by said undcrlap, and a cover fastened to the spurs of the said separate strips. 5. A chair bottom consisting of a sheet metal base formed with an underlap l around its edges a border-frame of strips of sheet metal, each strip formed With-integral spurs, one end ofeach strip adapted to be set` under said underlap, and the ends of oneparaliel pair of stripsA lap ing upon the ends ofthe other pair, and the strips so arranged that they will be separately and together clamped upon the base by said underlap.` t

6. In a chair-seat, the combination of a "metallic base having nderlapped edges,

with al separate border-frame aving integral cover attaching s urs and clamped to the base around its e ge ortion by means of said underlaps, the said border-frame having also integral lchair attaching tongues whereby the border' frame provides the .means offastening the cover to the base and the base at its 'under side to the chair-frame;
